2x Inventory + Dedicated Elytra Slot

This mod adds a second 27-slot inventory page to the player, letting you switch between your normal main inventory and an extra storage page with an up/down arrow button, while keeping the hotbar unchanged.

It also adds a dedicated elytra equipment slot, remembers which inventory page you were using across screens, and makes picked-up items go into the currently active inventory page.

NOTE: At some point, I will separate this into two individual mods so that players who wish to have the elytra slot but not the extra inventory space and vice versa can have the experience they desire.
